How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2. Weekly Synthesis
This week was based on a series of concepts. The concepts included, number sense,
numeration and mental computation. From studying these concepts within the lecture, tutorial
and textbook readings, my understanding and knowledge of these concepts developed. I had
gained an understanding upon how critical it is that children have number sense, knowledge
of numeration and place value, before learning formal concepts as they are are foundation to
all other concepts.
As a teacher I would ensure that my student’s understand these concepts before I introduce
them to any formal mathematical concepts such as addition and subtraction. This would be
done to establish student understanding and knowledge then progress to concepts and teach
appropriate thinking strategies for mental computation for addition and various other concepts
that are to be taught.
3. Concepts, Skills and
Strategies
Number Sense: https://www.youtube.com/watch?v=gVc-0jBM39o- this video depicts a detailed concept of number sense.
https://www.youtube.com/watch?v=KrmI_bO0Ru4 - this clip depicts various number sense teaching and thinking strategies
within a kindergarten setting and also displays strategies that can assist children with mental computation.
Numeration- The formal understanding of number and number notation. (specifying reading, writing, interpreting and
processing numbers)
Mental Computation – The understanding of operations in order to organise thinking as well as a foundation of knowledge of
basic number facts and strategies to process information. (Romina and Julie had explained within both lectures and tutorials
that children are able to use any thinking strategy they wish as long as it is effective, quick and accurate)
- https://www.youtube.com/watch?v=6ICQHxgL5ek
https://www.youtube.com/watch?v=9NX6-VXQ_Ew - Both of these clips depicted, portray mental computation in perspectives
using addition and subtraction.
Place value: The location of a digit in a number; the value of the digit is determined by its place.
4. The Language Model in Relation to Place Value
Symbolic
VerbalConcrete/Visual
Student Language
Materials Language
Mathematics Language
Symbolic Language
MAB blocks, matchsticks, bottle
caps (can represent different
numbers), sticks, paddle pop
sticks, toys (anything that can
be modeled)
Ones, tens, houses, places, how many,
trade, place holder, expand, out back
together
Introduction of term place value rather
than that of place value houses
Using place value mats, MAB
blocks, unifix cubes, charts,
visual representations of
strategies (charts – count-back
strategy, use ten etc) of concepts
Once children gain an understanding
upon numbers within place value house
they can learn to write the numerals.
(children build, read and write numbers
in a new house)
None are needed.
(place value mat &
MAB blocks are to
always be available if
children need them)
Concept: Place value refers to the location of a digit in a numeral.
Skills: children must have, number knowledge, numeration skills and mental computation skills
Thinking Strategies: Foundation of understanding upon the four base mathematical concepts
(+/-/x & division)
(For yr 3’s) This resource is an animation with
audio that models and compares sizes of three
numbers based on place value -
http://skwirk.com.au/esa/Place_Value.html
This source depicts various challenges
children are to solve with place value. -

5. Teaching Strategies
This source may prove to extremely useful for teachers as it is a 16 page guidance module that on introducing the concept of place value to years 1, 2, 3, and 4 students -
http://www.amsi.org.au/teacher_modules/Counting_and_place_valueK-4.html
This source assists students in building their understanding of place value by making and regrouping numbers and using those representations to then use +/- to solve them (ipad is
needed). - https://itunes.apple.com/au/app/number-pieces-basic-by-math/id611452042?mt=8
This resource is an interactive website that assists students in learning whole number and place value concepts through an adding game. -
http://www.curriculumsupport.education.nsw.gov.au/countmein/children_arrow_card.html
This source identifies numeration and the big ideas of what student’s learn and are to understanding within each year level from years 4 to 6,
http://eworkshop.on.ca/edu/resources/guides/NSN_vol_1_Big_Ideas.pdf
In relation to number sense, within this video a mathematics coach depicts ways in which number sense is defined and depicted within regular classrooms and how children can be
assisted within their developmental learning. - https://www.youtube.com/watch?v=HZdH6t7thfU
A useful resource that teachers can use is a resource called ‘Top Drawer teachers: Mental computation’, it contains sections that cover, the big ideas, teaching practices, student activities
and a section for downloads - http://topdrawer.aamt.edu.au/Mental-computation/Big-ideas
An example of a transcript of a question
being proposing to a child and observing
their responses and thinking strategies of
their mental computation. (in relation to
the last teaching strategy source linked)
6. Misconceptions
http://www.merga.net.au/documents/RP_Price_1998.pdf - This source identifies a common misconception that children
may have in relation to face value and place value. – e.g. 24 – a misconception that children may have may be that the
2 in 24 is viewed by only it’s face value rather than it’s place value.
Many misconceptions with mental computation are linked to both numeration and number sense as these two concepts
are to be understood to children before they develop mental computation strategies.
http://topdrawer.aamt.edu.au/Mental-computation/Misunderstandings/Learning-issues - this source depicts are variety
of detailed learning issues and misconceptions that student’s have in relation to mental computation that are linked to
numeration and number sense. Some of them including, number sense, place value, counting, pattern and structure.
Resolution to learning difficulties and misconceptions- This source depicts a diverse variety of strategic resolutions for
student’s misconceptions with mental computation. (Refer to the image below for some examples)
13. Additional Teaching
Resources
This resource can prove to be useful for teachers as it provides
constructed lesson plans, strategies and recommended steps to take for
the future. This resource is aimed mainly at assisting students that are
developing under the achievement standards for their year level with
mental computation

15. Chapter Summary
Chapter 10
Calculators- ‘All students should have access to appropriate technology as a means of both support and extend their mathematics learning experiences’.
Students should be encouraged to become intelligent/fluent with ICT and to be aware of limitations of the approach. (ready to adapt and respond to changes)
Student’s use of calculators shifts away from teacher centered approaches and reaches towards a more flexible student centered approach.
Teachers are to educate student’s upon the use of technology as calculators can raise student achievement.
Calculators reveal patterns which is a good method of practice for students to encompass as it will reinforce their skills and knowledge.
Mental Computation – ‘Calculations done mentally’
Using the ‘Big 7 Strategies’, such as, count on/back, use tens, doubles etc
Using place value with basic addition facts, combine basic facts
Many children apply written algorithms, mentally when asked to do mental computation
Guidelines for developing strategies – Encourage students to do computation mentally, learn which computations students prefer to do mentally, find out if
students are applying written algorithms mentally.
Front –end estimation – Checking the leading/front end digit in a number and the place value of that digit e.g. 4000/ 1213 + 2926 + 1578 (the answer would be
exactly 4000 if all digits except the front end ones were zeros – their not and so it must be more than 4000)
Compatible no. – numbers that go together – e.g. 7029 is close to 6900, and 69 is divided evenly by 23, so 23 and 69 are compatible.
